This invention refers to a special alimentary composition in the form of powder dilutable into water that is providing a suitable food for all persons (newborns, children, young and old people) who do not tolerate milk or soya proteins or lactose.

As a matter of fact statistics prove that a same person in addition to intolerance to cow-milk proteins, namely whey proteins and casein do not tolerate even the lactose because of a deficiency, either temporary or congenital, of lactase, that is the enzyme able to split the lactose into glucose and galactose and therefore to make it assimilable by the organism, according the feeding of these persons necessarily comprises lactose of cowmilk protein free products. In these products lactose is substituted with other carbohydrates like glucose or maltodextrins for newborns or with maltodextrins and starch for adults; the milk proteins on the contrary were replaced until now by alternative proteins like soya derived or hydrolized milk proteins. However these foods in addition to a bad taste that makes the same difficult to use, especially for prolunged administration as normally happens, cause several troubles either as regards of absorption of various nourishing components or for the outbreak of side effects.

The most important drawbacks are:

• allergy to the above mentioned alternative proteins;
• high osmotic load;
• metabolic acidosis;
• not appetising foods.

From what set forth it possible to deduce that, at present, no product is available to satisfy the nourishing needs of persons, newborns or adults having a lack of lactose or intolerance to milk proteins which product could provide all nourishing components in suitable amounts and without causing indesirable side effects.

Patent document WO 91/01647 discloses a hypoallergenic nutritional formula comprising meat selected for its low allergenicity, together with lipids and carbohydrate additives, and a vitamin and mineral content.

Particularly for newborns, the food of the invention can replace, in several cases, the troublesome parenteral feeding because it can be easily administered by gavage (in addition to feeding bottle).

The composition of the invention substitutes all the products used until now and has a formula that allows the feeding of subjects either with deficit of lactose or with intolerance to milk or soya proteins for long periods and without any indesirable side effects.

The invention provides a hypoallergenic food in which the proteins are constituted by hydrolized meat of a well particular type (white meat), a mixture of vegetable oils completely digestable and a mixture of carbohydrates (glucose, maltodextrins, starch) suitable for achieving a low osmolarity for the product.

To these components, minerals and vitamins are added in order to guarantee the necessary dietary allowance of these nourishments especially for newborns who are fed by this food only.

In particular, the product of the invention has the following composition with the weight percentages referring to the powdered product (100g). Fats 18 - 27 g Proteins 11 - 16 g Carbohydrates 48 - 64 g Minerals 2,0 - 3,4 g Moisture 2,2 - 3,8 g Ca 400 - 600 mg P 230 - 380 mg Na 180 - 300 mg K 400 - 700 mg Cl 380 - 650 mg Mg 50 - 85 mg Cu 260 - 450 µg I 28 - 45 µg Fe 5 - 10 mg Zn 3 - 6 mg Mn 30 - 60 µg Vit.

D 240 - 320 U.I. Vit. E 5 - 10 U.I. Biotin 15 - 35 µg Vit. K 30 - 50 µg

In the above product:
- the fat components are a mixture of the following oils in the following percentages of concentration in weight:

• 50-70% oil with high content of oleic acid (Trisun, Oleinate 181)
• 25-40% M.C.T. (middle chain Triglycerides) 0-10% soya-oil

The preferred formula of realization is as follows: Fats 23,0 g Proteins 13,2 g Carbohydrates 58,0 g Minerals 2,8 g Moisture 3,0 g Ca 500 mg P 274 mg Na 240 mg K 500 mg Cl 450 mg Mg 72 mg Cu 340 µg Fe 6,5 mg Zn 4,0 mg Mn 35 µg I 34 µg Vit.

In this formula:
- fat group is a mixture of oils at high content of oleic acid (Trisun, Oleinate 181) for 2/3 and MCT for 1/3. The composition could also contain a small amount of soya-oil also in order to guarantee the right contribution of linoleic acid and the right contribution and ratio between 3 and 6 that is important especially for newborns and babies;
- the carbohydrate group comprises: Precooked rice-starch 15% Maltodextrins 60% Glucose 25%
- proteins are exclusively obtained from hydrolized chicken or lamb proteins (or of other mentioned meats);
- minerals and vitamins are present in a such amount as to satisfy even the needs of newborn, as appears from table 1 where the data of the food are in comparison with those of the breast-milk and of a powdered adapted milk that can be found on the market: BREAST-MILK ADAPTED MILK 13% COMPOSITION MILK 14% Calories 70 67 69 Proteins 1,1 g 1,6 g 1,9 g Fats 4,0 g 3,7 g 3,4 g Carbohydrates 7,0 g 7,3 g 8,1 g Minerals 0,2 g 0,3 g 0,39g Mg 4 mg 5 mg 10 mg Ca 30 mg 55 mg 70 mg P 15 mg 35 mg 38 mg Na 16 mg 26 mg 33 mg K 52 mg 78 mg 70 mg Cl 38 mg 40 mg 63 mg Cu 3 µg 40 µg 47 µg Fe 0,05 mg 0,8 mg 0,9 mg Zn 0,3 mg 0,5 mg 0,6 mg I 3 µg 5 µg 5 µg Mn 1 µg 5 µg 5 µg Vit.

Moreover it is important to bear in mind that the mixture of oils, that constitutes the fat group of the invention, owing to the reduced contents of palmitic and particularly stearic acids, is easily assimilated even from newborns who receive also the necessary amount of essential fatty acids.

For these global characteristics of good assimilation for all its components and for the feeding almost without risks of side effects, the proposed product can be succesfully used even in malnourished babies which are refeeded with the greatest difficulty for getting in health conditions again. This is possible also because the proposed product can be given in a large range of aqueous concentrations (12-18%) so adapting either the global caloric intake or the intake of each single nourishing component to the needs of the babies to be nourished.

As a conclusion the advantages and purposes of the invention are in a great deal for the feeding of persons having intolerance to lactose or to the milk or soya proteins. The most important advantages are:

• to provide a food without any allergizzant component (i.e. any component that can lead to allergy), milk and soya proteins and lactose;
• to provide a food with a low osmotic load for the intestine (bowel) because its carbohydrates are provided for the greatest part in the form of polysaccharides;
• to provide a food that can adapt either the caloric intake or that of each single nourishing component to the individual needs;
• to provide a food that guarantee even to the newborns, the daily intake, both of minerals and vitamins required for having a good growth;
• to provide a tastefull and fine smelling food (on the contrary of other products used until today) and therefore suitable for feeding any person for long periods.
